The distance from the base of the arch to Priya is 528.6 feet.
Trigonometric ratio is used to show the relationship between the sides and the angles of a right angled triangle.
Let d represent the distance from the base of the arch to Priya, hence:
[tex]tan(50)=\frac{630}{d} \\\\d=\frac{630}{tan(50)} \\\\d=528.6[/tex]
